The study site was in the to use budget allocated for other development projects for Jatujak district of Bangkok. The study site selection was MSWM (DOE, 2014). Inefﬁcient MSWM is caused by many based on a number of criteria, including waste generation reasons along the management process chain. For example, quantity, the population, number of households, and total the time taken in the MSW transportation process is longer land area (Bangkok Statistics Report, 2013).
